From: Claudiu Manoil <[email protected]> Remove the DMCTRL Tx snooping bits (TDSEN and TBDSEN) as a workaround for LS1. It has been observed that currently the Tx stops functioning after a fair amount of Tx traffic with these settings on. These bits are sticky and once set they cannot be reset from Linux, for instance.
